摘要：
A new blind multiuser detector based on Differential Minimum Mean Squared error (DMMSE) criterion proposed in this paper is adapted to long spreading sequence DS/CDMA system with antenna array in frequency selective fading channel. By converting a frequency selective fading channel into several frequency nonselective fading subchannels, this detector avoids estimating the channel parameters and takes the desired user's spreading sequence as the perpetual training sequence instead of using pilot symbols. The simulation validates the better performance in serious fading channel existing strong MAI.
